WEED-DESTROYER.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed April 13, 1910. Serial No. 555,171.

To all whom it may concern:

Be it known that I, HERMAN THoENI, a citizen of the Republic'of Switzerland, residing at Spokane, in the county of Spokane and. State of lVashington, have invented certain new and useful Improvements in Weed-Destroyers, of which the following is a specication.

This invention relates to implements for exterminating noxious plants or weeds, such as dandelions and the like, and it is the object of the invention to provide a device of this kind which compact in form, readily portable, and easily operated by hand.

The invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, and in order that it may be better understood, reference is had to the accompanying drawing forming a part of this specification, in which drawing- Figure 1 is an elevation of the device,

partly broken away and in section. Fig. 2 1s a sectional view of the reservoir. Fig. 3

is a sectional detail of the clamp which secures the reservoir. Fig. 4t is a section on the line 11-4 of Fig. 1.

Referring to the drawing, the numeral 10 denotes a suitable reservoir, which, in the present instance, is in the form of a panshaped bottle. This reservoir is mounted on a penetrator 20 comprising' a stem which is tapered and brought to a point at one of its ends, so that it may more readily penetrate the weed. To the other end of the stem is fitted a suitable handle 17.

The reservoir is mounted on the penetrator by means of a metal band 11 which is fastened to the penetrator, and extends in a loop therefrom. The reservoir is placed in this loop, and is held therein by a shoulder 12 which engages the top edge of the looped portion of' the band, the shoulder being formed integral with the reservoir near its upper portion. The looped portion of the band also carries, in a bearing 13a thereon, a latch comprising a stem 13 rotatably mounted in said bearing, and having a projectingI finger 13b which is adapted to be swung over the top of the reservoir by the rotation of the stem. The finger carries a button to facilitate its manipulation.

The reservoir is formed with a downvwardly curved discharge spout 16 extending from the side thereof, and the top of the reservoir has a short neck which receives a stopper 14 having a small air passage 15 to allow the ready flow of the liquid from the reservoir out of the spout. In one side of the penetrator is a recess 23 into which the spout 16 extends when the reservoir is in position for use. From this recess leads a duct 19, one end of which is directly below the outlet of the spout when the latter is in the recess. The other end of the duct opens into a longitudinal groove 22 in the penetrator, said groove being made in one side thereof, and extending down to its point, at which it terminates. The recess Q3 is so .shaped that the spout may be readily placed thereinto, or removed therefrom. The reservoir is designed to contain a liquid of such character as to kill or destroy the weeds when applied thereon, or to the roots of the same.

ln operation, the reservoir is mounted on the penetrator as shown in Fig. 1. The device is then grasped by the handle, and the penetratoris pushed into the heart of the plant or weed at the root thereof, the pointof the penetrator entering the ground more or less, according to the depth of the roots.

The device is now tilted forwardly slightly,

and brought back again quickly, whereupon the liquid runs from the reservoir by the way of the spout into the duct 19, and down the groove 22 into the heart or root of the plant. In practice it has been found that a few drops sullice to kill an ordinary weed. The device must be inserted into the weed first before it is tilted, in order to prevent the liquid from coming into contact with other plants.

The device herein described is particularly useful for killing weeds on lawns and other places where boeing cannot be done, although it is obvious that it may be used with equal advantageous results wherever weeds are to be found.

l claim:

l. A weed destroyer con'iprising a penetrator having a recess on one side, alongitudinal groove terminating at one end of the penetrator, and a duct leading from the recess to the groove; and a reservoir mounted on the penetrator, and having a discharge spout extending into the recess.

2. A weed destroyer comprising a penetrator having a recess on one side, a longitudinal groove terminating at one end of Vupper edge thereof, discharge spout :extending into lthe aforetheqenetrator,` and a duet-,leading from -che recess to the groove; aband secured to the penetrator, and Vextendingl in af loop -therefrom; a reservoir removably mounted in `the loop, and having a shoulder engagngfthe seid reservoir having a said recess;` and a lat'ch carried by the looped
